Description

  The present invention relates to a security label, and relates to a security label that can determine the authenticity of a label itself, that is, can determine the authenticity of a product to which a label is attached.

  Conventionally, labels indicating manufacturers and distributors are sometimes affixed to machine repair parts and the like to indicate that these parts are proper and proper. This label guarantees performance and durability in addition to the manufacturer and distributor, but fraudulent acts such as attaching imitation labels with similar designs to similar products or bad parts (so-called imitation parts) are performed. There is a case.

  Due to the circulation of imitation parts, the machine manufacturer suffers not only monetary damage, but if bad parts are incorporated, the durability of the entire machine is not maintained, shortening the service life and causing failure and accidents. Furthermore, there is a problem that the trust of the manufacturer and the seller is impaired. Such an imitation act is a problem not only in machine parts but also in many fields such as clothing and bags, as well as software and electrical products.

  Such imitation or forgery prevention labels (security labels) have been developed. For example, there is a label using so-called black light ink that emits fluorescence when irradiated with ultraviolet rays. This label forms an image (print) on the surface with black light ink, and determines authenticity based on the presence or absence of fluorescence. However, depending on the type of printing paper, the gloss changes and the contour of the image can be visually observed, so printing with black light ink may be noticed.

  Other anti-counterfeiting labels include a label using a hologram and a method of printing micro characters. However, the former hologram has a high initial cost, requires special equipment, and increases the running cost. The latter micro-character is a technology that forms an image with minute characters to represent an image, but requires high-precision printing equipment and technology, and those costs are reflected in the label price, and the label is expensive. Become.

The present invention has been made in view of the above-described problems, and provides a security label that can easily determine the authenticity of a label at low cost and is effective in preventing forgery of the label itself and products, and preventing the distribution of counterfeit products. The purpose is to do.

  It is another object of the present invention to provide a security label that is difficult to notice that it is a security label itself.

The security label according to the first aspect of the present invention is a label in which a label piece composed of a label base material and an adhesive layer is temporarily attached to a release agent layer side of a separator having a release agent layer on at least one side. Has a notch penetrating at least the label base material among the label base material, the adhesive layer, and the separator, and the incision is a chain line composed of a short notch and a long notch. It represents the short and long points, and is characterized by displaying information and recording information.
As described above, the Morse code may be represented by a cut formed in the security label. Specifically, a short cut and a long cut form a chain line, and the short and long cuts express the short and long points of the Morse code. A short cut may be a short point, and a long cut may be a long point.
A security label according to a second aspect of the present invention is a label in which a label piece composed of a label base material and an adhesive layer is temporarily attached to a release agent layer side of a separator having a release agent layer on at least one side. Has a notch that penetrates at least the label base material among the label base material, the adhesive layer, and the separator, and the incision has a chain line shape, and the presence or absence of the incision corresponds to the black bar and white bar of the barcode It is characterized by representing numbers and / or letters .
In this manner, the cuts may be formed in a chain line, and the numbers and characters may be represented by making the presence or absence of the cuts correspond to the black and white bars of the barcode. For example, the cut portion is a black bar, the uncut portion is a white bar, and the thickness of the bar is expressed by the length of the cut portion or the length of the uncut portion. Conversely, the cut may be a white bar and the uncut portion may be a black bar. The bar code standard is arbitrary.

According to the security label of the present invention, it is possible to display information and record information by the shape, arrangement, position, number, or combination of the cuts formed in the label base material. Since the cut formed in the base material can be seen only at a meaningless cut, there is an effect that it is difficult to notice that the label itself is a security label even after the label is attached to the adherend.
When the cut reaches from the label substrate to the separator layer , the same cut is formed in the label substrate and the separator. Therefore, even after the label is peeled off from the separator and attached to the adherend, the same notch as the label substrate remains in the separator. Therefore, it also becomes possible to use the separators as a refrain.
Further, the cutting can be performed simultaneously with the half cutting of the label outline in the die cutting process of label processing, and the number of processes does not increase. No special equipment or materials are required, and no additional equipment is required.

The top view which shows another embodiment of the security label of this invention. The top view and sectional drawing which show the security label of this invention. The top view which shows another embodiment of the security label of this invention. The top view which shows another embodiment of the security label of this invention.

  Hereinafter, embodiments of the present invention will be described in detail. 1 and 2 show a security label 10 of the first invention of the present invention. 1A is a plan view of the security label 10, and FIG. 1B is a sectional view taken along the line bb. FIG. 2 is a perspective view of the label roll 12 in which a continuous body of security labels 10 is wound.

  The security label 10 of the present invention is adhered to the long strip-shaped adhesive paper 2 in which the label base material 5, the adhesive layer 6 and the separator 7 are laminated in this order from the label base material 5 side according to the outline of the label piece 4. A half-cut of a desired size reaching the agent layer 6 is performed at a predetermined interval, and an unnecessary portion called a label residue around the label piece 4 is removed. A cut 8 is formed in each label piece 4.

  As shown in FIG. 1B, the notch 8 penetrates the label base material 5 and the pressure-sensitive adhesive layer 6 from the surface of the label base material 5 and reaches the vicinity of the surface of the separator 7. The incision 8 is performed at the same time as the label piece 4 is punched out in the die cutting process of label processing. It is only necessary to add a blade for forming the cut 8 to the blade for punching out the outline of the label piece 4.

  The cuts in FIGS. 1 (a) and 1 (b) are Morse codes composed of combinations of short points and long points. The short cut and the long cut represent the short and long points of the Morse code. For example, the three cuts in FIG. 1 (a) represent the letters A, B, and C in order from the top of the figure. The number of characters may be one character or a plurality of characters, and not only a combination of characters and numbers but also a word or a sentence can be expressed as long as the security label 10 has enough space.

  The security label 10 is printed with characters and designs on the surface, for example, a so-called “genuine label” indicating that the contents of the container with the label attached, or the attached article itself is genuine or genuine. It may be used as a “genuine label”.

  When writing different information on the security label 10 one by one, the continuum is wound to create the label roll 12 shown in FIG. 2, set on an electronic printer, and printed on the surface. Hereinafter, how variable information is printed by an electronic printer will be described.

  FIG. 3 is a schematic side view of the electronic printer 50. The electronic printer 50 includes a roll paper supply unit 51 and a printing unit 61 provided in a housing 52. The label roll 12 is rotatably supported on the shaft 55 of the roll paper supply unit 51. A guide bar 56, a paper sensor 57 for detecting the presence / absence of a continuous body of the security label 10, and a pitch sensor 58 for detecting a label interval are attached along the travel route of the security label 10. The downstream printing unit 61 includes a platen roller 62, a thermal head 63 that presses and holds the continuous body of the security label 10 together with the platen roller 62, and a cutter unit 64 downstream thereof. The housing 52 is provided with an issue port 65 adjacent to the cutter unit 64.

  When the platen roller 62 rotates, the label continuum 6 unwound from the label roll 12 passes through the guide bar 56, the paper sensor 57, and the pitch sensor 58 to the printing unit 61, and the heat generated by the thermal head 63 on each security label 10. Images such as characters and barcodes are printed by scanning. The security label 10 on which the printing has been performed continues or is cut by the cutter unit 64 and reaches the outside through the issuing port 65, and the label is issued. The security label 10 issued and printed in this manner is peeled off from the separator 7 and attached to a predetermined adherend.

  When a third party sees the security label 10 attached to the adherend, the cut 8 is not noticed at first glance. This is because the notch 8 is thin and difficult to see, and it is unlikely that the notch 8 is intentionally formed. Even if a third party notices the presence of the incision 8, it is only recognized to the extent that the label is scratched. Since it is difficult to guess until the notch 8 has a meaning, it is unlikely that the meaning of the notch 8 is interpreted.

  When a malicious person attempts to counterfeit the security label 10, use a base material with a texture similar to that of the label base material 5, print the preprint color, font, and design on the label processing machine to the same size. Expected to finish. However, if the presence of the incision 8 is not noticed, a label without the incision 8 is forged. Therefore, even if a product to which the forged label is affixed goes around, the authenticity can be determined using the presence or absence of the incision 8 as a clue. It is conceivable that the forger of the seal processes the same notch 8 in the label base material 5, but since the notch 8 is difficult to accurately imitate the position and depth unlike printing, it has the effect of suppressing forgery. can get. Even if forgery including the cut 8 is attempted, it is difficult to create a label having the same configuration, and authenticity determination is possible.

  Further, the Morse code indicated by the continuous label cuts 8 may be changed at a constant cycle by utilizing the meaning of the position, shape, and arrangement of the cuts 8. For example, in the case of a three-sheet cycle, the first sheet is A, the second sheet is B, the third sheet is C, the fourth sheet is returned to the first A, and the fifth sheet B and the sixth sheet C may be repeated. In this case, labels representing A, B, and C are each one third of the total number of sheets, and labels representing A, B, and C are evenly included in the same lot of the product that is the adherend. Become.

  When a malicious counterfeiter creates a label with a notch 8 meaning “A” and affixes it to the counterfeit product, authenticity can be determined by performing a sampling inspection of a lot of suspicious products. For example, if there are 100 suspicious products, about 10% of them may be extracted and the meaning of the cut 8 may be examined. If it is a genuine product, the ratios of the cuts A, B, and C are substantially uniform. If the cuts of all labels are only A, or if only A and B appear, it is estimated that the entire lot is a counterfeit product.

  FIG. 4 shows another embodiment of the first invention of the present invention. The security label 10 in FIG. 4 is obtained by pre-printing characters 9 on the surface of each label piece 4. A cut 18 is formed at a position adjacent to the character 9. The cut 18 is a simple line segment, and the position where the cut 18 is formed represents information. In the security label 10 of FIG. 4, cuts 18 are formed below the letter A and below the number 2, and A and 2, ie, a combination of letters and numbers, correspond to specific information. The combination of letters and numbers is arbitrary. They may be combined one by one, a combination of one character and a plurality of characters, a combination of a plurality of characters and one character, or a combination of a plurality of characters and a plurality of characters.

  FIG. 5 shows a security label according to the second aspect of the present invention. 5A is a plan view of the security label 10, and FIG. 5B is a sectional view taken along the line bb.

  Similarly to the security label 10 of the first invention described above with reference to FIG. 1, the security label 10 of the second invention has a long belt shape in which the label base material 5, the adhesive layer 6, and the separator 7 are laminated in this order. The adhesive paper 2 is used. Similarly, it is formed by half-cutting to a desired size and punching into a predetermined shape. Moreover, the cut | notch 28 is formed from the label base-material 5 side similarly to 1st invention.

  As shown in FIG. 5B, the cut 28 penetrates the label base material 5 and the pressure-sensitive adhesive layer 6 from the surface of the label base material 5 and reaches the layer of the separator 7. By making the blade height of the blade for forming the cut 28 higher than the blade for forming the label contour, the deep cut 28 is formed.

  FIG. 5C shows a state where the label piece 4 is peeled off. When the label piece 14 is peeled off, a cut 28 a appears in the remaining separator 7. Since the shapes of the cut 28 and the cut 28a are the same, the information that the cut 28 has, such as Morse code, can be deciphered by looking at the cut 28a of the separator 7. Therefore, in the security label 10 of the second invention, in addition to the effects of the first invention, the separator 7 in which the cut 28a is formed can be used as a copy of the label piece 4.

  Note that the depth of the cut 28 may penetrate the separator 7 or stay in the middle of the layer as long as it reaches the inside of the layer of the separator 7.

  FIG. 6 shows an embodiment in which a binary number is expressed by a notch 38. As shown in the figure, each label piece 4 is provided with a plurality of cuts 38 parallel to the longitudinal direction (label arrangement direction). If the cut 38 is formed in a certain section P, the section 38a is set to “1”. If another section P is a portion 38b with no cut, that section is set to “0”. The cut 38 shown in FIG. 6 becomes “111001011” in binary, and various information can be expressed by converting this into decimal. For example, it may represent a date or a product lot number. Here, the section 38a in which the cut is formed may be expressed as “0”, and the section 38b in which there is no cut may be expressed as “1”.

The security label 10 shown in FIG. 7 is an example in which a cut 48 corresponding to the barcode 70 is formed. As shown in the figure, a chain line-shaped cut 48 is formed in each label piece 4. Of the bar code 70, a part corresponding to the black bar 78a is represented as a cut part 48a, and a part corresponding to the white bar 78b is represented as a part 48b having no cut, thereby representing numbers, characters, and the like. The thickness of the bar is expressed by the length of the cut portion 48a or the portion 48b having no cut. The meanings of the black bar 78a, the white bar 78b, and the cut 48 may be reversed. The bar code standard is arbitrary.

  The depth of the cut in the embodiment shown in FIGS. 6 and 7 may not reach the separator 7 (first invention) or may reach the layer of the separator 7 (second invention).

  The shape of the cut may be a straight line or a curved line, but it is desirable to form it as parallel or almost parallel to the label transport direction as much as possible. When a plurality of cuts are provided, the positional relationship between the plurality of cuts on the label is also arbitrary. Although the position and the arrangement may be meaningful, it is desirable to arrange them in parallel or substantially in parallel with the label transport direction. The risk of tearing or tearing is reduced during label processing or when printing is issued by a printer.

  The cut may be arranged at any position on the label. .

  The number of cuts is arbitrary. Even if it is expressed by one, letters and numbers may be expressed by a plurality of combinations like Morse code.

  In the first and second inventions, the type and material of the label substrate 5 are not particularly limited, such as paper or synthetic resin film, and are generally used as adhesive paper. For example, a paper substrate such as fine paper, coated paper, art paper, synthetic resin film made of PET (polyethylene terephthalate), PE (polyethylene), PP (polypropylene), PS (polystyrene), or the above synthetic resin A composite sheet obtained by combining a plurality of types and a synthetic resin film and paper can also be used. Thermal paper may be used.

  The pressure-sensitive adhesive of the pressure-sensitive adhesive layer 6 is, for example, an emulsion system (in which the pressure-sensitive adhesive is dispersed in water), a solvent system (in which the pressure-sensitive adhesive is dissolved in a solvent), a hot melt system (using thermoplasticity), or the like. is there. Examples of the material include adhesives such as synthetic rubber, natural rubber, acrylic resin, polyvinyl ether resin, urethane resin, and silicone resin. The adhesive strength of the adhesive is arbitrary.

  The separator 7 is a general purpose one. For example, there may be mentioned paper or film coated with a fluorine-based release agent in addition to ultraviolet curable silicone, thermosetting silicone, solvent silicone, alkyl pendant polymer.

  It should be noted that the present invention is not limited to the above-described embodiments, and it is obvious that each embodiment can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, arrangement, and the like of the above-described constituent members are not limited to the above-described embodiment, and can be set to a suitable number, position, shape, and the like for carrying out the present invention.
